function TemporaryEnchantFrame_Hide()
    if ( BuffFrame.numEnchants > 0 ) then
        BuffFrame.numEnchants = 0;
        BuffFrame_Update();

The function is missing the third button.

When the player is in a vehicle the TempEnchant3 button will pop up because TemporaryEnchantFrame_Update() is not called.

Function should look like this

function TemporaryEnchantFrame_Hide()
    if ( BuffFrame.numEnchants > 0 ) then
        BuffFrame.numEnchants = 0;
        BuffFrame_Update();     
    end
    --Hide enchants
    for i=1, NUM_TEMP_ENCHANT_FRAMES do
        _G["TempEnchant"..i]:Hide();
        _G["TempEnchant"..i.."Duration"]:Hide();
    end
end
